JAMES K. MCGUKIN, 0E NEWARK, NEW JERSEY.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 392,214, dated November 6, 1888. Applica-tion filed January 14, 1888. Serial No. 260,681. (No model.)

To /LZZ whom it may con/cern:

Be it known that I, JAMEs K. MOGUKIN, of Newark, in the county of Essex and State of NewJersey,haveinventedanewaud Improved Shutter-Vorker, of which the following is a full, clear, and exact description.

My invention relates to an improvement in shutter-workers, and has for its object to provide a simple, cheap, readily applied, and effective article,whereby a shutter may be held partially or entirely open, and which may be conveniently operated from the room with the windows closed.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar letters of reference indicate corresponding parts in all the iigures.

Figure l is a transverse section through a portion of a window casing and a blind, illustrating the application of theinvention. Fig. 2 is a longitudinal section through the applied device. Fig. 3 is a transverse section taken on line 3 3 of Fig. 1, and Figs. 4 and 5 are enlarge'd detail views.

In carrying out the invention, A represents the sill of a window, a the inner projecting portion, and a the usual beading. Transversely the sill at each side and through the beading a tube, B, is projected supported in any approved manner at its outer end upon the sill, as illustrated at a2 in Fig. I, which tube outside the said beading is open on top.

Vithin the outer tube, B, a second tube, D, is concentrically arranged, the inner tube being of a diameter to readily slide in the outer tube and provided at its closed inner end with a longitudinal spirallytwisted bore, b, within which bore a spiral rod, D', is entered, the movement whereof is limited by a suitable stop, in order that the rod may not be turned entirely from its casing.

Upon the inner end of the spiral rod Dl a knob, d, is rigidly secured, and upon a spindle fastened to said iiXed knob a second knob, d', is held to revolve, as illustrated in Fig. 2. The end d2 of the rod D adjacent to the fixed knob l is of a diameter equal to the diameter of the tube D, for a purpose hereinafter set forth.

In the end of the outer tube, B, upon the top a transverse slot, e, is out, (shown more clearly in dotted lines in Fig. 4.,) and upon the tube at this point a collar, E, is secured by a set-screw or otherwise, provided upon the upper side With an aperture, e', registering and extending parallel with the said slot e. The upper apertured section of the collar projects beyond the body at each side, which projections are provided with aligning segmental recesses e2 and e3. Through lthe aperture e a cylindrical rod, H, is projected provided with a concavity, h, in one face, which concavity is designed to register with the slot e. The rod H, designed to act as a cam, is retained in position by a pin passing through one end and a hinged handle, h', at the opposite end, and the revolution of the cam is limited by contact of the aforesaid piu and handle with the side Walls of the recesses elz and e3, as shown in Figs. 3 and 4. When the cam is in a locked positi0n,the handle h hangs perpendicularly downward, as shown in Figs. 3 and 5, and enters a slot, h2, whereby it is kept from lateral movement. To the outer end of the inner tube at the top an upwardly-inclined strap,k,isbrazed, soldered, or otherwise attached, adapted to project outward from the tube, to which one end of a radial bar, K, is pivoted, the other' end of said bar being pivoted to a plate, 7c', fastened to the inner face of the shutter near the hinged side.

In operation, the shutter being closed, as in Fig. 2, the cam-handle is turned from the position illustrated in Fig. 5 to that shown in Fig. 4,which brings the cavity in the cam-rod over the slot in the outer tube, whereby the inner tube is left free to slide. The loose knob is now grasped and the spiral rod drawn out its length as far as desired. This having been effected, the xed knob is grasped and the rod pushed outward,which movement carries with it the inner tube,which acting upon the radial bar opens the shutter back, as illustrated in Fig. l. The enlarged end of the spiral rod Will have now entered the outer tube, and upon turning the cam-rod to its first position (illustrated in Fig. 3) the same is caused to bind IOO upon the enlarged surface, holding the spiral rod in a fixed position. In closing,the emu is released7 the spiral rod drawn inward, thecaiu aga-in locked upon the inner tube, und the spiral rod is run into the saine.

Then the device is used in connection with heavy shutters, the twist of the rod and the rod-casing may be graduated to suit the emergency without departing from the spirit ofthe invention. The knobs may also be oruainented or plain, or of' any preferred construction.

'Having thus fully described luy invention, I claim as new and desire to secure by Letters Patent-- 1. lu nshutter-Worker,the combi11atiou,with nn outer tube or easing, of an inner concentric tube having a spirnl bore, n radial arm attnehed to the inner tube, a spiral rod ndnpted tothe bore of the inner tube and provided with a knob, and means lfor clamping said inner tube and rod7 substantially as shown and described.

2. In a shuiter-w0rker,the coiubination,\vith an outer tube or easing and au inner sliding` tube having a spiral bore, of a spirnl rod working` in the bore of' the inner tube and provided with a fixed knob on its outer end,and a loose knob pivoted ou the outer surface of' the fixed knob, substantially as described.

3. In a shutter-Worker,the co1nbinati0n,with an outer tnbehaving n slot near theinuer end, of an inner concentric tube having a spiral bore, n radial arm attached to said inner tube at the outer end, a spiral rod entering the spiral bore of the inner tube provided with a knob7 a horizontally apertured collar fixed upon the outer tube over the slot, and n cumrod rotating in the collar und inthe slot of the outer tube, substantially as shown and described.

4. In a shutter-worker,the coxnbination,with an outer tube or easing having n transverse slot and a sliding tube in the outer tube or casing, of a collar secured to the said easing or outer tube over the slot therein, and a rod having a cevity in one side fitted to turn in the said collar and provided with a handle, substantially as described.
